You're leaving out many details.  But based on this:

-.- Mystic BBS v1.12 A48 (Windows/32)

I'm making the assumption that you are using the DX menu command and in turn were using DOSXTRN/SBBSEXEC to provide a virtual UART.  This only functions under Win32.  Under Windows 64 that COM port is not present and thus Windows will throw the error when the door attempts to open it.

You'll need to first reconfigure LORD to use FOSSIL.  Then, download and install NetFoss64 (start with version 1.25).  Once you have both set up, change the menu to run command DD to call nf64.bat and in turn load LORD.
